题目1
Optimal pricing schemes in the presence of social learning and costly reporting
报告摘要
We study a monopoly’s optimal mechanism design problem in which consumers each arrive sequentially and choose one of binary actions consisting of an arm with unknown utility. Both the monopoly platform and the subsequent consumers learn from the consumer feedback, but providing feedback is costly and hence the platform has to offer bonus to motivate feedback. We characterize the optimal bonus scheme together with the optimal pricing scheme of the platform whose goal is to maximize the profit. There are four types of scheme in total: Full Coverage, Partial Coverage, Immediate Revelation and No Bonus. Discriminators among each scheme reveal trade-off that the platform faces in the optimal design.

题目2
Screening with public information disclosure
报告摘要
We study a model in which a monopolist (she) has multiple items for sale to a unit-demand buyer (he) with private information and she designs the selling mechanism and the public information disclosure rule to maximize her expected revenue. We find out that, the optimal mechanism resembles a recommendation mechanism: upon receiving each signal, the buyer knows which one of the items is of the highest quality realization and is persuaded into buying this item if his type exceeds the cutoff level.
